    You can use windows firewall to do the same thing if you can't figure out your router settings

    No you can't, the OS firewall is independent to the network firewall. You'll need to use NAT to map the local IPv4 address to the inbound port. Once the local address is mapped, you then have to allow the connection to be made at the client level (Windows firewall).

    The reason NAT exists is because there aren't enough addresses to give each device in the world its own unique IP, so you have a WAN address and then NAT (network address translation) maps your internal network to the public facing IP via ports. IPv6 solves this by having a much bigger address space thus each device can have a unique IP and thus port mapping isn't required.

    Edit: @OP add me on Discord and i'll try help you out. KieranDevvs#1512
